The World Well: Blood of Caro

Action RPG set in Redimus, a world where magic and technology mix alongside vampires and an active slave trade. You play a young girl who finds a magic gun after her home burns down, then sets out for revenge. The game takes place in 814 R.E., just before a major war breaks out. Expect jungle environments and night-time exploration as you track down whoever destroyed your life. The magic gun presumably shapes combat, though specifics aren't detailed. The setting blends fantasy elements with firearms and suggests a darker tone given the slavery and vampire presence. If you're after a revenge story with supernatural weaponry in a morally murky world, this could land.
